SIDE-SPRING VEHlCLE.

SPECIFICATION forming part of Letters Patent No. 274,390, dated March20, 1883.

Application filed June l5, 188:2. (No model.)

To all whom it may concern:

Be it known "that I, CYBUS NV. SALADEE, a citizen ofthe United States,and a resident of Torrington, in the county ot' Litcheld and State ofConnecticut, have invented certain new and useful Improvements inVehicles, of which the following is a specification.,

Mynvention consists inanew and improved mode ofconstructing and applyingside springs to vehicles, as hereinafter fully described, and has forits object to admit of the vertical movement of the body withouttilting, while carrying the body at 4a point directly below thecross-center of the seat.

In the drawings, Figure 1 is aside elevation of so much of a buggy as isnecessary to show my invention applied.

3 is a diagram to illustrate the main points of improvement secured bymy invention.

By reference to Fig. 3 it will be seen that the vertical line Ncoincideswith the center of the body midway between the axles, and with thecentral point of attachment of the spring, and that line O coincideswith the center ofthe seat. As the weight carried in these vehicles ison the seat, the line O will indicate to what extent the load must beback oi' the point of attaching the spring to the body, and shows thatthe spring does not support the body at that pointwhere the greatestpart ot` the load is carried, and hence the liability (so common in thisclass of wagons) of the rear end of the body to bang or sag lower thanthe front end when loaded and in motion. l overcome this defect bygiving to the rear halt of the spring substantially the form seen inFig. 1, whereby to project the spring farther to the rear, and supportthe rear half of the body directly under the seat on the line O. Theside spring is made ot' two sections, as shown, or-in one piece, and byextending the spring back of the axle and turning it to its point ofsuspension to the rear of the axle length is secured to insure a safeand easy spring-support. tion, l), of the spring cannot be of the sameformas theu rear section, as in that case' it would be struck by thefront axle as the lat- Fig. 2 is a plan viewv 'of the bottom ot' thebody and gear, and Fi g.

The front sec- I ter is turned in turning the vehicle. This secf tiontherefore must be of substantially the form ot' a true semi-ellipticspring. It' this latter form were duplicated for the rear half of thespring, it `would necessitate the use ot a link to' admit of theelongation of the spring under pressure; but in the, construction shownthe curved end of the rear half, C, ot the spring permits the elongationof the spring and a free and easy vertical movement of the body. Thefront ends of the springs are jointed to irnmovable shackles on the`front bar, and the rear ends to immovable' pivots at the rear of therear axle, thus permitting vertical motion of the body, but'no tiltingthereof.

I propose sometimes to use the rear sec tions, C, Fig. 1, but with across-spring, D'. (Shown in dotted lines.) Said cross-spring may be ofany suitable character, and applied to the side bars and bodyin theusual way. These springs are equally weil adapted to either the'ordinary side-spring or to the side-bar77 gears now in general use, and1 intend to use them in both classes of wagons.

I claim- 1. The combination, in a vehicle, of a body, frame,and sidesprings havingagreater length between their points of suspension thanthe distance between the bolster and axle, and connected to the body tosupport the same at a point nearest the rear end, with the front endspivoted to stationary shackles and rear ends pivoted at therear of therear axle, substantially as set forth.

2. A vehicle having side sprin gs, each in two l sections, the frontsections bent to substantially true semi-elliptical form and pivoted toto this specification in the presence of two 9o OOURTNEY A. COOPER, A.E. T. HANSMANN.
